Abstract
A constant velocity coupling 10, 305 which rotabably connects an input shaft 11 to an output shaft 12 by means of a control mechanism or control system 21, 309 which, in particular forms, includes a gimbal arrangement comprised of an inner yoke 22 rotatably connected to an outer yoke 16. The control mechanism including control yoke 21 constrains at least portions of the coupling to lie on or in association with a homokinetic plane 300 of the coupling. In particular forms the control mechanism operates symmetrically about supplementary angle bisector 308.
Claims21
1-87. (canceled)
A constant velocity coupling wherein the conditions for equal instantaneous transfer of angular velocities between an input and an output shaft are maintained by a control mechanism, said coupling comprising,
- (a) an input shaft rotation axis
- (b) an output shaft rotation axis
- (c) a control mechanism,
- said control mechanism adapted to constrain at least portions of said coupling so as to achieve a constant velocity characteristic;
- said control mechanism based on spherical geometry with respect to a geometric centre defined as the intersection of said input shaft rotation axis and said output shaft rotation axis.
